Title: Surface acoustic wave element
Inventor: OKAMOTO TAKESHI
IPC: H03H9/25
Filed: 1989-06-23
Abstract: PURPOSE:To attain highly efficient operation by forming a zinc oxide film having a tilt less than a specified value with respect to a silicon layer face with a specific film thickness onto a silicon layer of a face cut off on nearly equivalent to the (110) plane and using a Sezawa wave as a surface acoustic wave element. CONSTITUTION:A dielectric film 7 made of a silicon dioxide or the like is formed on a silicon substrate 5 cut at a face equivalent to the (110) plane. A zinc oxide film 6 is formed on the substrate 5 and the film 7 so that its film thickness (h) is in a range of 0.9<2pih/lambda<3.0 with respect to a wavelength lambdaof a surface acoustic wave and a piezoelectric axis is tilted less than 10 deg. from the direction perpendicular to the face of the substrate 5. When a Sezawa wave is excited as a surface acoustic wave in a direction equivalent to the direction of the (011) axis of the substrate 5 to the input electrode 8, the surface acoustic wave propagates on the surface of the film 8 and reaches an output electrode 9. Thus, the electromechanical coefficient is increased and the element is operated with a high efficiency.

Filed: 1982-09-20
Abstract: PURPOSE:To detect even apparent power together with reactive power and to detect active power with high precision, by adding a circuit which detects the apparent-power by using the output voltage (e) of a signal synthesizing circuit. CONSTITUTION:The output voltage (e) of the signal synthesizing circuit is used to find the reactive power Eq by a mean value amplifying circuit 2 and further, a rectified mean value amplifying circuit 3 is used to find the apparent power Es. The circuit 3 rectifies the voltage (e) on full-wave basis and then obtains the mean value in at least a one-cycle period to output the electric power Es. In this case, a severe method of finding the active power Eq by arithmetic Ep= (E<2>s-E<3>q)1/2is not employed and an approximate value is found by a simple method. Namely, an absolute value circuit 4 finds the absolute value of the reactive power Eq, and an operational amplifying circuit 5 finds the difference in absolute value between the apparent power Eq and reactive power Eq and outputs it as the active power Ep.

Filed: 1988-06-29
Abstract: PURPOSE:To achieve high throughput by providing a cylindrical lens between an objective lens and a linear sensor, processing signals obtained from said linear sensor and detecting the position of an alignment mark. CONSTITUTION:A wafer 15 and a mask 14 are overlapped with each other by a gap 18 of several tens mum. In the right and left upwards in a slantwise direction from the wafer 15 and mask 14, there are provided an illuminating optical device 5 and a detecting optical device 10 confronting each other. An illuminating angle 19 of incident light from an optical axis of the device 5 for a normal line of the mask 14 or wafer 15 is selected to be equal to a slantwise detecting angle 20 of an optical axis of the device 10. The illuminating light and detecting light are thus inclined for the mask 14 and wafer 15. Therefore, alignment marks 16, 17 within an X-ray exposing region 13 can be detected without moving the devices 5, 10. Furthermore, because the device 10 is placed outside an optical path of the region 13, the marks 16, 17 can be detected even during the exposing time, and it is not necessary to move the device 10 at every alignment; thereby, high throughput can be achieved.

Abstract: PURPOSE: To prevent the thermal damage of a lighting circuit component stored in a cover by making the diameter of a member fitted to the opening section of the cover larger than the diameter of the cover. CONSTITUTION: The diameter of a member fitted to the other end opening section of a cover 1, e.g. the diameter of a member 6 supporting a fluorescent lamp 15 or a covering member 18 of the fluorescent lamp 15, is made larger than the diameter of the cover 1. The high-temperature ascending air current generated by the heat emitted from the lamp 15 or the heat emitted from the surface of the covering member 18 of the lamp 15 rises on the periphery apart from the surface of the cover 1. The heat radiation from the surface of the cover 1 is not impeded, the ratio that the ascending air current heats the cover 1 is reduced, and a lighting circuit component can thermally be protected.

Abstract: PURPOSE:To improve the acceleration performance and acceleration feeling and obtain the simple constitution by automatically changing the speed change point to the high speed side until a specific condition is satisfied, when the throttle opening degree less than a prescribed value continues for a prescribed time. CONSTITUTION:A control unit 4 operates a shift solenoid 6 according to the signal state supplied from a throttle sensor 2 for detecting the opening degree of a throttle valve and controls the operation of a hydraulic controller 8. When the throttle valve is held in a low opening degree for a prescribed time, a speed change point map is changed to a power map from a common speed change map until a prescribed time lapses from the time when the speed change point is changed or until the throttle opening degree becomes over a prescribed value. When the throttle opening degree less than a prescribed value does not continue for a prescribed time, the common speed change map is used. Therefore, the acceleration performance and acceleration feeling can be improved, and the simple constitution can be obtained by reducing the number of parts.
